Yes. If the EGR temperature sensor malfunctions, it can cause cylinder temperatures to rise, which can cause engine ping or knock. This is an indicator that there is a problem with the combustion process. Any problem that results in engine ping or knock should be tended to as soon as possible, as engine knock can cause serious engine damage if left unchecked.
